Hello R users, I'm analyzing an experiment in a balanced incomplet block design (BIB). The effect of blocks are assumed to be random, so I'm using nlme::lme for this. I'm analysing another more complex experiments and I notice some diferences from doBy::popMeans() compared multcomp::glht() and contrast::contrast(). In my example, glht() and contrast() were equal I suspect popMeans() are doing something diferent. This a proprosital difference? Does popMeans account the variance of random effects or something similar? The code below is reproducible, for eas...

Hello, I haven't been able to find an example for the second case below -- or perhaps I didn't recognize it when I saw it. Is there a value for x such that svalue(x) will return "bbb", either by itself or as part of an array? Or do I need to do something else entirely?

...stand what they are, I have absolutely no idea how to a) calculate them in R and b) how to use them to impute my missing values in R. Again, I've searched the mail lists, internet and literature and have not found any documentation to advise on how to do this - I'm lost. I've looked at popMeans, but have no clue how to use this with predict() - if this is even the route to go. Any advice would be much appreciated. Note that YEAR will be treated as a factor and not a linear variable (i.e., the relationship between COUNT and YEAR is not linear - rather there are highs and lows about every...

I have data that looks like this: > df1 group id 1 red A 2 red B 3 red C 4 blue D 5 blue E 6 blue F I want a list of the groups containing vectors with the ids. I am avoiding subset(), as it is only recommended for interactive use. Here's what I have so far: df1 <- data.frame(group=c("red", "red", "red", "blue",
